You can find the timeline on the detail card of records for Deals, Offers, Orders and Projects .
What is the timeline
In the Timeline are displayed records that are linked to the original record (for example, a Deal here). The timeline is located on the detail card of the record in a separate tab.
For example, in the Timeline of a Deal, you can find Calls where you discussed the specific Deal with a Client. See the image below.
You can view the timeline all at once or by individual sections. If you are only interested in Calls, in the separate tab Linked Records select the drop down Activities » Calls.
You also have buttons Add (green plus) and an icon for Export. From the Client History, you can easily create a new Activity or a Deal.
If you want to display all attachments related to a specific record and part of the Timeline, click on the tab Linked Records » drop down Activities » Attachments.
